uClibc-based targets can load their programs in an offset in memory, and

well, not to be pedantic, but this is for FLAT programs, not uClibc
We have a target that uses loadmaps as opposed to the above mechanism.
It is just another ptrace request, but it doesn't use linux_read_offsets
at all.
you mean FDPIC ? gdb already supports that and uses a different set of ptrace
requests for that. ideally, gdb nor gdbserver should not be tied to a specific
file format (what format it happened to be compiled for). instead, gdbserver
should support all formats and then gdb detects the format and changes its
requests based on that.
